God is the Creator and Preserver of the entire universe, all living beings that exist, visible and invisible. He is also the Supreme Judge and Absolute King of it all. He must, He can, and He will maintain perfect and absolute justice for all things and people for all times and places. Justice holds it all together. If even one injustice was ever allowed and unaccounted the foundations would crumble, chaos would ensue, and the universe cease.
But even us flawed humans can see that injustice is rampant and justice for the defenseless is seldom administered rightly in our world. Injustice is even carried out in the heavenly council of the gods which humans cannot see. The Psalm gives a glimpse into the invisible council that affects earthly affairs and shows that God is in charge. If so, we can rest assured that the supreme Judge will put everything to rights some day, some way.
Therefore, we can rest comfortably under the control and kingship of our loving and just Lord and Savior, Jesus Christ. We can trust that our spiritual enemies will not gain unfair advantage over us and that He is in charge of our lives for our good. It’s all OK.
